Question

ADH or vasopressin is

• A. Enzyme that hydrolyses peptides
• B. Hormone secreted by pituitary that promotes reabsorption of water from glomerular filtrate
• C. Hormone that promotes glycogenolysis
• D. Energy rich compound connected with muscle contraction

Answer 1

The correct option is B Hormone secreted by pituitary that promotes reabsorption of water from glomerular filtrate

Anti diuretic hormone (ADH) or Vasopressin is a peptide hormone composed of nine amino acids. It is secreted from the posterior part of pituitary gland. This hormone increases reabsorption of water in kidneys and this results in decreased rate of urine production. Other functions of this hormone are contraction of arterioles and capillaries, reducing heart rate and stimulating micturition.

So, the correct answer is 'Hormone secreted by pituitary that promotes reabsorption of water from glomerular filtrate'.
